LAMP SOCKET.

Application led November This 'invention pertains -to an electricalfitting and more particularly the construction of Va lamp socket for usein vehicle lamps or the like embodying a reflector" and a vvsocketsecured thereto for vsupporting a lamp bulb. j j

The principal feature of the invention resides in a structure of thecharacter described which provides a simple and economical manner ofrigidly and permanently securing 'the lamp socket and reflectortogether. j

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims.

Fig. 1 is a central vertical section through thelamp socket' and aportion of the reflector.: Fig. 2 is a rear elevation thereof.. f Fig. 3is a side elevation thereof.

' In the drawings there is shown a portion of a reflectorv 10 of theusual character in which a lamp socket 11 is mounted. Said socket isprovided with the usual bayonet slot 12 and has an opening in the rearend thereof for receiving the electrical connection or wire 13 which isattached to an insulating disc 14 slidably mounted Within `said socket.The compression spring 15 is positioned intermediate said disc and therear end of the socket' for maintaining the same under spring pressurein electricalcontact with the lamp bulb not shown herein.

'The socket is formed cup shaped of a single piece of metal drawn intosuitable cylindrical shape provided with a central opening in the rearend thereof while the front end is open. Said socket is formed with anannular outwardly extending bead 16 adapted to abut against the forwardsurface of the reflector 10 when the socket is mounted there/in. @verthe rear portion of the socket there is acup shaped retaining member 17conforming in shape to that portion of the socket over which it ismounted,

said member having the edge surrounding its open end abutting directlyagainst the rear surface of the reflector 10. Atone point a'iout thebead 16 there is a latterly'extending portion 18 stamped therein which-projects through a slot formed adjacent the opening of theJ reector andinto a corre- 2o, 192e.. serial no. 149,605.

spondingslot 19 formed in the forward end of the member 17. Thus thesocket, reflector and member 17 arelocked.againstrotation with respectto"-\each other. l'

After the socket has been placed in posi- :tion with respect to thereflector and the members rigidly together in position toI clampthemselves within the reflector. It will be noticed that said eyeletforms a suitable opening through which the conduit may extend. f

The invention claimed: v i

- 1. In a lamp socket, a support therefor having an opening throughwhich the rear `of said socket extends, a projection extending outwardlyfrom said socket in position to abut against one surface of the support,a clamping member. formed over the rear portion of said socket inposition to engage against the opposite portion of said support wherebysaid support will be clamped between said member and said projection,and an eyelet clamped through the rear adjacent ends of said socket andmember for securing them rigidly, together and providing an openingtherethrough.

2. In a lamp socket, a support therefor .having an opening through whichthe vrear of said socket extends. a peripheral bead formed about saidsocket intermediate its ends i-n position to abut against the forwardsurface of the support, .a cup-shaped clamping member conforming to theshape of said socket and mounted over the rear portion thereof inposition to have its forward edge abut the rear surface of said support,and

ingmemher conforming to the shape of said sot-liet' und mounted over therear portion thereof in poeition to have its forward edge :lhut the renr surface of Saittsupport, an eyelet adapted to secure the rear ends ofsaid lQoc'ket and member together and haring an opening therein throughwhich n Conduit may extend, and means for interlocking said socket,support and member for preventing their relative rotation.

In Witness whereof, I have hereunto alfxed my signature.
